RULE FREEZE FOR THIS VOLUME

With reference to paragraph A.13 of Volume ABR:

In all classes, the two-year rule for no changes to model aircraft/space model specifications,manoeuvre schedules and competition rules will be strictly enforced. For Championship classes,changes may be proposed in the year of the World Championship of each category.

For official classes without Championship status, the two-year cycle begins in the year that thePlenary Meeting approved the official status of the class. For official classes, changes may beproposed in the second year of the two-year cycle.

This means that in Volume Space Models:

(a) changes can next be agreed at the Plenary meeting 2012 for application from January 2013;

(b) provisional classes are not subject to this restriction.

The only exceptions allowed to the two-year rule freeze are genuine and urgent safety matters,indispensable rule clarifications and noise rulings.

PART TWO SPACE MODEL SPECIFICATIONS

A space model must comply with the following requirements prior to launch, operation and flight.

2.1 WEIGHT

Gross or maximum weight, including space model engine or engines shall in no event exceed 1500grams. It will be specified separately for each class in these rules.

2.2 PROPELLANT

No more than 200 g of propellant materials shall be contained in its space model engines nor shalltheir total impulse exceed 160 Newton-seconds (Ns).

2.3 STAGES OF OPERATION

2.3.1 There shall be no more than three (3) operable stages. A stage is defined as a portion of the modelairframe containing one or more space model engines that is designed to separate or which actuallyseparates from the model while in flight. An un-powered part of the model is not considered to be astage. The configuration of a model is considered to be that of the model at the instant of first motionon the launcher. Engines ignited simultaneously are considered one stage regardless of the numberof separated parts; for example Soyuz.

2.3.2 Total impulse of engine(s) in a lower (booster) stage must, for safety reasons, be equal or greater thantotal impulse of engine(s) in (any) of upper stage(s). The thrust of the booster stage also must beequal or greater than the thrust of each of the upper stages. This does not relate the strapped-onboosters which are ignited simultaneously with the booster stage.

2.4 CONSTRUCTION REQUIREMENTS

2.4.1 A space model shall be so constructed to be capable of more than a single flight and shall contain ameans for retarding its descent to the ground so that its structure may not be substantially damagedand so that no hazard is created to persons and property on the ground.

2.4.2 A space model must not eject its engine(s) in flight unless it/they is/are enclosed in an airframe that

will descend in accordance with the provisions of paragraph 2.4.1. The engine(s) of the models cannotbe fastened by glue and cannot be an integral part of models construction.

2.4.3 Construction shall be of wood, paper, rubber, breakable plastic or similar materials without substantialmetal parts. Models of Classes S1, S2, S3, S6, S9 and S10 must have minimum diameter of 30 mmof enclosed airframe for at least 50% and for Class S5 for at least 20% of the overall body length. Incase of Class S1 the smallest body diameter must be not less than 18 mm for at least 75% of theoverall length of each stage, including their back sections. No boat tails or reducers are allowedunless they meet this requirement.

2.4.4. Minimum dimensions of subclasses of classes S1, S2, S3, S5, S6, S9 and S10 must not be less than:

Event Class

Minimum diameter (mm)

14/62



4.3 LAUNCHING

4.3.1 Organisation

During all operations concerned with the launching and flight of space models, all authority for thesafety and conduct of operations on the flying field shall be vested in a range Safety Officer who mustbe a member of a National Airsports Control and who must be 18 years of age or more. DeputyRange Safety Officers who meet the above qualifications may have this authority delegated to themby appointment from the Range Safety Officer, but this delegation or partial authority does not relievethe Range Safety Officer of overall responsibility and authority on the flying field.

Adequate opportunity and facilities will be provided so that all competitors in each event at acompetition may obtain engines and prepare their models simultaneously for flight under theobservation of officials.

4.3.2 Flight Permission

All space models presented for operation on the flying field shall be permitted or denied flight by theRange Safety Officer or his duly authorised deputy on the basis of his considered judgement withrespect to the possible safety of the model in flight.

4.3.3 Launching Device

A launching device or mechanism must be used that shall restrict the horizontal motion of the modeluntil sufficient flight velocity shall have been attained for reasonably safe, predictable flight. Alaunching angle of more than 60 degrees from the horizontal must be used.

4.3.4 Assisted Launch

A launcher must not impart to the model any velocity or change of momentum except that caused bythe space model engine(s) contained in the model. A launch assisted by mechanical devices built intothe launcher shall not be allowed.

4.3.5 Launching Procedure

Launching or ignition must be conducted by remote electrical means at a safe distance that dependson the space model class, weather conditions and number of spectators. It shall be announced by theRange Safety Officer before the beginning of competition in a particular class of the model and mustbe fully under the control of the person launching the model. All persons in the vicinity of the launchingmust be advised that a launching is imminent before a space model may be ignited and launched, anda minimum five (5) second count down must be given before ignition and launching of a spacemodel.

4.3.6 Weather Conditions

See General Rules for International Contests, Para B.14 and B.15.

4.3.7 Hazard

A space model in flight shall not create a hazard to aircraft and shall not be used as a weapon againstground or air targets.

4.3.8 Thermal Creation and Detection

4.4.2 Model Marking and Identification

Each entry shall carry, prominently displayed upon its body, fins, or other exterior part, thecompetitors FAI license number in letters and numbers approximately one (1) centimetre high. Thename, national insignia, or international identification mark (see Section 4b, Annex B.2) of thecompetitors nation must be displayed on the exterior of the model.

A light coloured area of minimum dimensions 1 cm by 3 cm must be provided for the organisersprocessing mark.

4.4.3 Builder of the Model

The judges shall make every reasonable effort to insure that each competitor has completelyconstructed the model entered in the competition with construction to be interpreted as the actionrequired to complete a model starting with no more prefabrication than the amount used in theaverage kit. Models that are completely prefabricated or require only a few minutes of unskilled effortfor their completion shall be excluded from competition. Materials and design may be obtained fromany source, including kits.

4.5 OFFICIAL FLIGHTS

4.5.1 Definition of an Official Flight

A flight is considered official if the model or any part of the model leaves the launching device, losescontact with the launching device after ignition, or becomes airborne, except in the case of acatastrophic failure according to the provisions of Rule 4.6.3., in which case the flight is not consideredofficial.

4.5.2 Number of flights

In each event, except Scale (S7), each competitor shall be given an opportunity to make three (3)official flights, time and weather permitting. In Scale (S7) two (2) opportunities will be given, time andweather permitting.

4.5.3 Definition of an Unsuccessful Attempt

An attempt is classed as unsuccessful if the model or any part of the model leaves the launching

device and at least one of the following events occur:a) model collides with another model during the flight,

b) proven frequency interference for radio controlled models,

c) catastrophic failure according to the provisions of the rule 4.6.3,

d) no close or track lost for altitude models.

If this happens on the first attempt then the competitor is entitled to the second attempt.

4.6 DISQUALIFICATION

4.6.1 Judges may disqualify any model at any time which, in their opinion, does not comply with thecompetition rules or which the Range Safety Officer or his authorised deputy feels may not be

reasonably safe in operation.

4.6.2 Judges may disqualify any competitor on the grounds of failure to practice or observe reasonablesafety measures, published or otherwise, for poor sportsmanship, for failure to abide by the orders ofthe Range Safety Officer or his authorised deputy or for misconduct in general.

4.6.3 A model experiencing a catastrophic failure which, in the opinion of the judges, was not due to orcaused by improper design, construction, or pre-flight preparations of the model, shall not bedisqualified from competition. A model suffering such a catastrophic failure and thereby renderedincapable of additional flights may be replaced by another model. For Scale models S5 and S7,experiencing a catastrophic failure, see rule 9.12.

4.6.4. By reason of flight characteristics, a model may be disqualified for a flight but is not necessarilydisqualified for the entire event.

4.8.2. The timing of flights is limited to a maximum determined by the individual class and size of engineused. The total flight time is taken from the models first motion on the launching device to the end ofthe flight.

4.8.3. The total time of the three flights of each competitor is taken for the final classification.

4.8.4. In order to decide the winner when there is a tie, additional deciding flights shall be made immediatelyafter the last flight of the event has been completed. The maximum time of flight in each additional

round shall be increased by two (2) minutes on the maximum time of flight of the previous round.There shall be only one attempt for each additional flight. The times of the additional flights shall notbe included in the final figures of classification for teams, they are for the purpose of determining thewinner and for awarding the prizes attached to the title. The organiser will decide the time duringwhich all competitors must launch their models. In the case of a tie in the team classification, the bestindividual score (classification) will be used.

There shall be no more than two fly-off rounds to determine the winner. The second fly-off round willbe timed to the completion of the flight for final results.

4.8.5. For World and Continental Championships a round is defined as the amount of time allocated by theorganiser for a national team to prepare and launch their models for one official flight per teammember (one hour is recommended).

4.9. ALTITUDE DATA

For measuring and calculating altitudes may be used the method based on the principles oftriangulation, the method of electronic or radar tracking or the method based on calculation of theheight where the horizontal distance of tracking lines of pairs of stations in space achieves theirminimum.

4.9.1 Triangulation Method

4.9.1.1 Tracking

All models in any event for which an achieved altitude figure is scored shall be tracked in flight be atleast two (2) calibrated measuring devices which are situated on a measured baseline of at least three

hundred (300) metres. The distance to the launch pad shall be a minimum of 2/3 (two thirds) of thecurrent world record rounded to the nearest lower 100 metres.

At world championships, a redundant tracking system shall be implemented with four measuringdevices (Theodolites), two at each tracking station. The best tracking pair will be designated as theprimary trackers and their data will be used first. If the primary trackers fail, the data from thesecondary trackers will be used. If they fail, the combination of azimuth and elevation from eachtracking station will be used.

For models with engines over 20 Newton-seconds the base line must be a minimum of 450 metres.The distance from the launch site to the centre line of the base line must be 1/2 the base line length.

The distance to the launch pad shall be at least 300 m for models with up to 2,5 Ns impulse. Thelaunch site must be seen from the measuring devices.

4.9.1.2 Tracking Accuracy

The measuring devices must be able to measure angles in both the horizontal (azimuth) and vertical(elevation) axes and shall have a minimum accuracy of +/- 0,5 degrees in both azimuth and elevation.

4.9.1.3 Tracking Procedure

A model for which an achieved altitude figure is required will be tracked aloft visually by measuringdevice operators manning each tracking device until they see that the model has reached the

maximum vertical altitude of its flight. The angle of azimuth from the baseline and the angle ofelevation from the horizontal shall then be read to the nearest degree of arc and reported to thelaunching area.

Angular data thus recovered from tracking will be reduced to altitude data by use of the principles oftriangulation.

4.9.1.4 Computed Altitude

The computed altitude from each stations reduced altitude data must be within ten percent (10%) ofthe average altitude computed utilising data from both stations. Computed station altitudes not fallingwithin 10% of the average computed altitude will result in a no close (NC) for the model. All altitudeswill be rounded-off to the nearest metre before this 10% rule is applied. The official scored altitude isthe computed average altitude.

A Track Lost (TL) is recorded where the trackers are unable to determine the position of the modelsufficiently to obtain any angles.

A zero is recorded if the flight path is erratic, unpredictable, malfunctions or the flight is disqualified forsafety reasons.

In the event of a No Close (NC) or a Track Lost (TL) for the model, the competitor may be allowedto fly again until the end of the round. The organiser is obliged to announce altitude calculations ofeach flight not more than ten minutes after the launch, to leave modellers whose flights are consideredNo Close (NC) or Track Lost (TL) enough time to make another flight in the same round. A safetydisqualification or a model malfunction making the model difficult to track will result in a zero for theflight.

4.9.1.5 Visibility of Models

All models that are to be tracked for altitude shall disperse a coloured powder at ejection which will aidtracking. Theodolite operators may lose track of models which do not contain sufficient powder orcontain powder which does not contrast well with the sky. The organiser will have tracking powderavailable for competitors use.

4.9.2 Electronic or Radar Tracking

Altitude data derived from electronic or radar devices is valid only if evidence is presented regardingproper calibration and correction.

4.9.2.1 Electronic altitude measurements

Electronic altimeter carrying requirements and application:

a) An electronic altimeter carried in a space model shall be completely enclosed and contained withinthe model, so as to be removable. It shall not be capable of separating from the model in flight.

b) An electronic altimeter shall fulfil the following technical specifications:

- Must use barometric measurement technique.

- Must record, as the flight altitude, the difference between peak altitude achieved and thealtitude of the pad from which it was launched.

- Have a data readout resolution of 1 metre or better.

- Have a measurement accuracy of 2% of the recorded altitude or 2 metres, whichever isgreater.

- Have a data sampling rate of 10 samples per second or greater.

- Give the data readout of peak altitude by audio or visual means directly from the altimeter,with no external device required.

- Must be capable of being completely cleared of all previous flight data before flight.

9.1. DEFINITION

Scale competition is a single event and is limited to flying space models that are true scale models ofexisting or historical guided missiles, rocket vehicles, or space vehicles.

9.2. MULTI-STAGE PROTOTYPE

If the entry is a scale model of a multi-staged vehicle, it may be designed so that one or more of theupper stages are inoperable dummies. However, the upper stage of a multi-staged vehicle may not beentered and flown without its operable lower stages unless specific data is furnished to the judges toprove that the upper stage configuration was designed to be or has flown separately, alone, and as avehicle itself. For example, all Aerobee rockets must have operable boosters.

9.3. SELECTION OF PROTOTYPE

The competitor must have modelled one particular serial-numbered prototype, except in the casewhere the prototype is in such large mass production that there is no single individual vehicle that canbe singled out for scale modelling purposes. However, the competitor shall make every reasonableattempt to model a specific prototype.

9.4. PROOF OF SCALE

The competitor must supply scale data to substantiate his models adherence to scale in dimension,shape, colour, and point pattern. Minimum allowable data consists of length and diameter of theprototype and one photograph. Further data is certainly encouraged. Dimensional data must be froman accurate source such as magazines, books, manufacturers specifications or data sheets, etc.Photographs from any sources are acceptable. All data presented should apply to the particularprototype that is modelled and entered. Judges may deduct points for incorrect data.

9.5. KITS

Flying scale space model kits may be used as a source of design, materials, etc. and acceptable forentry only if accompanied by scale substantiation data other than that contained in the kit or availablefrom the kit manufacturer. The competitor shall be responsible for ascertaining the correct scalequalities of the kit and must present satisfactory evidence that the kit model is correct to scale.

9.6. STABILISING FINS

Scale models of rockets, missiles or space vehicles that are not fin-stabilised may be fitted withtransparent plastic fins so as to make the model stable in flight while detracting the least from thescale qualities of the model

9.7. PLASTIC MODEL KIT PARTS

Parts from plastic model kits may be used on scale space models provided that this use is pointed outin the data presented with the model at the time of judging for scale qualities.

9.8. CONDITIONS OF MODEL FOR JUDGING

Models will be judged for scale qualities in flight condition minus space model motors. All clear plasticfins, launching lugs, and fittings and other flight items must be attached to the model for scale judging.Nothing may be added to or taken off the model between the scale judging and the flight except spacemodel motors and recovery device packing.

Part Nine Scale Competition (Class S7)


9.10. NUMBER OF FLIGHTS

Each entry must make a stable flight, and two (2) opportunities will be available to the competitor forthis purpose, time and weather permitting.

9.11. SCALE JUDGING

Scale quality points will be awarded to each entry according to the following schedule:

9.11.1. A competitor who presents the following proper technical data may be awarded a maximum 50 points:

authentic, authorised drawing(s) of the prototype with at least ten dimensions and three crosssections, i.e. data which define colour of cross sections and markings on it;

workshop drawing of scale model - scale 1:1;

at least one colour photograph of the whole prototype with clearly visible details of colour andmarkings;

at least three photographs of details and assemblies;

file containing all necessary technical data.

9.11.2. Adherence to scale: 250 points maximum. To be considered as a scale model the dimensions of thebody diameter, overall length, overall fin span (if finless, use body length) should not depart from scaleby more than 10% or else the model is disqualified. The judging category should be judged in three

areas: 1) body and nose cone - 125 points maximum; 2) fins - 75 points maximum; 3) colour andmarkings - 50 points maximum. This rule shall not be applied to dimensions less than 5 millimetres

For models with clear plastic fins see Annex 9, Cat. Scale Adherence, Sub-Cat. Fins

9.11.3. Workmanship: 350 points maximum. To be judged on neatness, care of construction, and degree offinish. The judging category will be judged in two areas: Workmanship of nose cone, body, fins anddetails: 200 points maximum and Finish of nose cone, body and fins 150 points maximum. Goodworkmanship that detracts from scale-such as a high gloss finish on a model that should have a flat ordull finish - will detract from maximum points.

9.11.4. Degree of difficulty: 200 points maximum. To be judged on the degree of difficulty involved inconstructing the model. Factors to be considered include symmetry of model. Number of externalcomponents, intricacy of paint pattern, degree of detailing, and degree of difficulty in adapting the

model for flight conditions.

9.11.5. Flight, characteristics: 300 points maximum. To be judged on launch, stability of flight, staging (ifany) and recovery. A competitor has to designate which operations his models are to perform in flight(e.g. separation of stages. radio controlled trajectory, ejection of payload, etc.).

If the model has been disqualified in both official flights, the competitor will not be eligible for finalclassification.

9.11.6. In the case of World and Continental Space Modelling Championships dimension deviations from theScale shall be measured by a separate qualified measuring team approved by the FAI Jury. Themeasured dimensions will be presented to the Scale Judges for verification and included with theScale Judging Data.

9.12. Should the model experience a catastrophic failure, be incapable of additional flights (4.6.3.) and havescored no Flight Characteristic points, the competitors static scale points will be taken to decide finalclassification.

Part Ten Scale Altitude Competition (Class S5)


PART TEN - SCALE ALTITUDE COMPETITION (CLASS S5)

10.1. DEFINITION

This series of events involves altitude competition with scale space models and is a combination ofthe altitude competition (Part 5) and the scale competition (Part 9). The objective of the competition isto achieve the highest altitude with a scale space model.

10.2. RULES

All entries must comply with the rules of Scale competition (Part 9) and will be judged under the samerules and receive the same number of maximum scale quality points except that three flights will beallowed and no flight characteristics points will be given.


10.3. SCORING

The total number of scale quality points awarded to an entry will be added to the highest officialaltitude achieved by the entry. Only in the case of no close or track lost, no altitude points areadded but the flight is considered qualified and the competitors static points will be taken to decidethe final classification. Otherwise, if the model does not make a qualified flight after three attempts, thefinal classification will be zero.

The entry having the largest number of total points resulting from adding the static scale quality pointsto the altitude in metres achieved from the same flight, will be declared the winner. In the event of atie, the points gained for scale quality will be decisive.


The judges must disqualify from scale altitude competition any entry which, in their opinion, does notshow sufficient scale qualities or evidence of normal level of workmanship required for a scale modelunder the provisions of the scale competition (Part 9). The intent of this rule is to eliminate from scalealtitude competition any entry which has scale qualities grossly subordinated in favour of altitudeperformance qualities.

11.7.4.4. One point will be awarded for each full second of flight time up to a maximum of 360 points (that is,360 seconds maximum).

11.7.4.5. One point will be deducted for each full second flown in excess of 360 seconds.

11.7.4.6. Additional points will be awarded for landing:

When the nose of the model comes to rest within one metre of the centre of the designated landingcircle, 100 points will be given. 10 points are deducted from the maximum of 100 points for everyfurther metre from the centre. If the nose of the model lands between marks it is the lower of the

marks that counts.

No additional points will be awarded if the landing occurs 390 seconds after the start or if the modellands outside of the designated landing circle. If, on landing, the model hits the pilot or his helper, orthe pilot stops the model, no additional points will be awarded for landing.

For each flight, the total score is compiled by adding points for flight time and additional points forlanding.

11.7.4.8. The winner of a particular flight in the relating group receives a score of 1000 points. Othercompetitors receive points as follows:

Part Eleven Radio Controlled Rocket Glider Time Duration & Precision Landing Competition (Class S8E/P)


11.7.4.9. The five competitors with the highest scores after three starts qualify for the final round.

There will be one final flight for a group consisting of all participants of the final round.

. If there is a frequency conflict, the competitor with the worst score in three qualifying flights mustchange the frequency of his radio.

11.7.4.10. The final classification will be determined by the sum of all flight scores of each competitor.

When there is a tie, the best score of one round shall be used to determine the individual winner. If afurther tie occurs, the second best score of one round shall decide the winner.

11.7.5. ORGANISATION OF STARTS

11.7.5.1. Competitors shall be combined in groups by draw in accordance with radio frequencies used to permitas many flights simultaneously as possible. For this competition, there must be a minimum of threecompetitors in a group. The draw is organised in such a way that, as far as possible, there are nocompetitors of the same nation in the same group. The flying order of the different groups is alsoestablished with a draw. A different composition of groups shall be used for each round.

11.7.5.2. Each group is entitled to three minutes of preparation time before the starter gives the order to countoff the working time.

11.7.5.3. Each group of competitors has 14 minutes of working time to collect transmitters from the official,

perform an official fight and return the transmitters to the official. In the case of the working time beingexceeded (a delay in returning the transmitter to the official), the competitor will be disqualified for theround.

Note: Working time can be repeated at the Contest Directors discretion for any unforeseen reasonoutside the competitors control (for example, radio interference). The working time shall be repeatedimmediately after the end of the current round.

11.7.5.4. The starting order of competitors in each group will be determined from the order in which competitorsannounce their start to the range safety officer. In the case of a misfire, the competitor is allowed torepeat the start only after the attempts of all competitors registered for start at the time of his attempt.

S8E/P LANDING AREA

In normal situations the circles will overlap each other but the centres should never be closer than 5metres apart. In normal practice, the circle centres should be 10 metres apart as in the diagramabove.

12.1. GENERAL

Gyrocopter Duration Competition comprises a series of events open to any single-staged space modelwhich uses the principle of auto-rotation as the sole means of recovery.

12.2. PURPOSE

The purpose of this competition is to achieve the longest flight duration using an auto-rotatingrecovery system.

12.3. SPECIFICATIONS

12.3.1. Each entry must be decelerated during descent by its auto-rotating recovery device. The resultingautorotation must be around the roll axis of the auto rotating recovery device and must be the result ofproper deployment and operation of the recovery system.

12.3.2. Flexible materials can only be used for covering rigid support members. The recovery system shall notbe constructed solely, or in part, of flexible materials and rigging (e.g., a parachute with rigid stringersor folding rotors of flexible materials between rigid stringers). entries using a recovery system which is

designed to act (or which actually acts) in a manner similar to a parachute, a rigid inverted bowl, orsimilar techniques are specifically excluded from this competition.

12.3.3. The entry may not separate into two or more unattached parts, and shall be disqualified if it does so.

12.3.4. The 50% requirement of Rule 2.4.3. applies.

Established records, for any class of model for which new rules or rule changes apply, such that theperformance of that class of models is affected in any way, shall be retired whenever those new rulesor rule changes become effective.

14.2. SURPASSING PREVIOUS RECORD

Attempts to surpass an established record must exceed by one percent (1%) the value of theestablished record performance.

All models used for establishing or surmounting of the existing record must correspond to allregulations of Part 2 of the Sporting Code, Section 4, Volume SM.

14.3. HOMOLOGATION REQUIREMENTS

In addition to the standard FAI homologation data, the following special space model recordhomologation requirements must be met by any record claimant.

14.3.1. The competition flight card of the submitted record attempt shall be marked, Record Attempt.Tracking station angular data must be entered in ink. The name, signature, license number andaddress of the record claimant must appear, written in ink, on the contest card. The following data,entered in ink, must also appear on the contest flight card: competition sanction number, event inwhich the record attempt was flown, date of record attempt, location of record attempt, certifyingsignatures of three witnessing judges, a signed statement certifying the calibration and accuracy of thetracking system used, and a statement signed by the three judges giving the make, type andmanufacturer of the engines used in the attempt.

14.3.2. In the case of parachute/streamer duration record attempts, the three witnessing judges must submit asigned statement giving size, material and design of the parachute used.

14.4. HOMOLOGATION DATA

The record claimant must submit the following homologation data:

a). An accurate drawing to scale of the model used in the record attempt, said drawing to includeall principal dimensions, gross weight, and burnout weight.

b) A clear, glossy photograph enlargement of the model used in the record attempt with a ruler,hand, or other object of known size appearing in the photograph indication size of the model.

c). The record dossier should contain the completely filled out forms as shown in tables IIthrough V as far as applicable to the class concerned.

14.5. JUSTIFICATION

It is the purpose of homologation procedures and requirements to ascertain as well as possible that agiven model did indeed attain the flight performance claimed and that the flight was made within therequirements and standards of this Sporting Code. The many factors involved in the flight of a spacemodel require that the above additional data be submitted to confirm a record attempt. In unusualcircumstances, the FAI may request additional substantiating data to insure that these purposes havebeen achieved.
